Multiattack

The glabrezu makes two pincer attacks.

Pincer

Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 16 (2d10 + 5) bludgeoning damage. If the target is a Medium or smaller creature it is grappled (escape DC 17). The glabrezu has two pincers each of which can grapple one target. While grappling a target a pincer can't attack a different target. If the same creature is grappled by both of the glabrezus pincers it must escape from each of them separately.

Wish

Once per 30 days the glabrezu can cast wish for a mortal using no material components. Before doing so it will demand that the mortal commit a terribly evil act or make a painful sacrifice.
